[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, but not all the embodiments of the present application.

[0051] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0052] Embodiment 1:

[0053] Figure 1 The shell 300 is located at the entrance position of the robot into the base station, and has two pincer-shaped side portions 303 which extend outwardly. If the existing excess material shearing scheme is used, it is difficult to find a good balance point among positioning accuracy, cutting effect and clamp cost. Therefore, the present application provides a shell excess material shearing device 100 for cutting Figure 1 the excess material 301 of the shell 300 shown.

[0054] Please refer to Figures 1-6 The shell excess material shearing device 100 of the present application comprises a fixed plate 1, a positioning assembly 2, a clamping die 3 and a shearing assembly 4. The shearing assembly 4 is installed on the fixed plate 1, and the positioning assembly 2 is arranged at the end of the shearing assembly 4.

[0055] The positioning assembly 2 comprises a static die 21, a positioning plate 22 and a limiting column 23. The static die 21 and the positioning plate 22 are arranged parallel to the fixed plate 1, and an installation area 24 is formed between the static die 21 and the positioning plate 22. In order to fix the static die 21 and the positioning plate 22 on the fixed plate 1, a plurality of supporting rods 12 are arranged between the static die 21, the positioning plate 22 and the fixed plate 1, so as to reduce the overall volume of the static die 21 and the positioning plate 22. The shell 300 has a plug-in portion 302, the shell 300 abuts against the limiting column 23, and the plug-in portion 302 is inserted into the installation area 24. As shown in Figure 1 The plug-in portion 302 is a plate body of the shell 300 itself for strengthening the structural strength of the shell 300 itself, and the excess material 301 of the shell 300 is arranged on the plug-in portion 302. By inserting the plug-in portion 302 into the installation area 24 and abutting the shell 300 against the limiting column 23, the shell 300 is coarsely positioned in the positioning assembly 2.

[0056] The clamping mold 3 is arranged on the mounting area 24 and is drivingly connected to the pressing mechanism 8 and moves away from or close to the shell 300. When the shell 300 needs to be clamped and positioned, the clamping mold 3 moves downward and presses the shell 300 so that the plug-in part 302 continuously inserts into the mounting area 24 until the shell 300 is clamped and pressed by the positioning assembly 2 and the clamping mold 3. After the shell 300 is positioned by the static mold 21 and the positioning plate 22 of the positioning assembly 2, the shell 300 is accurately positioned so that the cutting position of the excess material 301 is close to the shearing assembly 4.

[0057] The end of the shearing assembly 4 is located at the bottom of the mounting area 24 and is used to cut the excess material 301. When the clamping mold 3 positions and clamps the shell 300, the shearing assembly 4 cuts the excess material 301 of the shell 300 to complete the shearing function of the device. During the shearing process, the shearing assembly 4 shears the excess material 301 upward, which coincides with the downward pressing force range of the clamping mold 3. Therefore, when the excess material 301 is cut, the two forces do not deflect on the shell 300, the position of the excess material 301 is not easy to elastically deform and deviate, and the cutting quality of the excess material 301 is excellent.

[0058] In use, the plug-in part 302 of the shell 300 inserts into the mounting area 24, the shell 300 abuts against the limiting column 23 to complete the rough positioning, the pressing surface 31 of the clamping mold 3 presses the upper end of the shell 300 until the plug-in part 302 is inserted into the mounting area 24, the shell 300 is clamped between the positioning assembly 2 and the clamping mold 3, the shearing assembly 4 cuts the excess material 301 to complete the cutting work. Then the clamping mold 3 is reset in reverse, and the shell 300 can be taken out by external force.

[0059] Further, the positioning assembly 2 further comprises a shearing baffle 26, as shown in Figure 4 The shearing baffle 26 is drivingly connected to the pressing mechanism 8 and moves to the top of the excess material 301 before the shearing assembly 4 shears the excess material 301. The shearing assembly 4 generally has a shearing knife 41 and an actuator such as a pneumatic cylinder or an electric cylinder for driving the shearing knife 41. When the shearing knife 41 shears toward the root of the excess material 301, the end of the excess material 301 away from the plug-in part 302 deflects upward due to uneven force. If the shearing knife 41 directly cuts the excess material 301, the cut mark at the root of the excess material 301 is uneven and not beautiful after shearing. When the shearing baffle 26 moves to the top of the excess material 301 and then shears, the shearing baffle 26 resists the deformation of the end of the excess material 301, so that the shearing knife 41 shears a flat and beautiful surface.

[0060] In some embodiments, the top of the positioning plate 22 has a positioning groove 221, and the shell 300 has a protrusion 304 matched with the positioning groove 221. When the shell 300 is placed in the mounting area 24, the protrusion 304 falls into the positioning groove 221.

[0061] The positioning groove 221 and the protrusion 304 are arranged, the shell 300 can be better positioned on the positioning assembly 2, so that the accuracy of the coarse positioning is higher, and the precise positioning effect is better. At the same time, considering the stress capacity of different pincer-shaped sides 303, when the mold 3 is clamped and pressed to push the shell 300, the positioning groove 221 and the protrusion 304 can reduce the possibility that the limiting column 23 is pressed to damage the pincer-shaped side 303 due to the large placement error of the coarse positioning. As shown in Figure 5 In order to further improve the accuracy of the coarse positioning, the positioning assembly 2 has a symmetry axis Y, and the positioning groove 221 is symmetrically arranged on the positioning plate 22 along the symmetry axis Y. The protrusion 304 is also symmetrically arranged with the positioning groove 221. In actual application, the protrusion 304 can be an internal structural part of the shell 300, or a connecting part for splicing between base station shells.

[0062] Considering that the number of excess materials 301 is actually two in the embodiment, in order to facilitate processing, the shearing assembly 4 is also symmetrically arranged with two along the symmetry axis Y. Of course, in other embodiments, the shearing assembly 4 can adopt a mode of driving two shearing knives 41 to realize the simultaneous cutting of two excess materials 301 at the positions of the two excess materials 301.

[0063] In some embodiments, the limiting column 23 is arranged at both ends of the static mold 21 and located on the side away from the mounting area 24, the shell 300 has a pincer-shaped side 303, when the insertion part 302 is inserted into the mounting area 24, the inner side of the pincer-shaped side 303 abuts against the limiting column 23. Through the abutment of the two limiting columns 23 and the inner side of the pincer-shaped side 303, and the insertion of the insertion part 302 into the mounting area 24, a positioning combination of “two points and one line” is formed, so that the coarse positioning of the shell 300 is accurate, and the shell 300 is more conducive to the accurate positioning and cutting in the later period.

[0064] In some embodiments, as shown in Figure 6 The static mold 21 and the positioning plate 22 are respectively provided with first positioning faces 211 and second positioning faces 222 on the side facing the mounting area 24, when the shell 300 is pushed into the mounting area 24, the first positioning face 211 and the second positioning face 222 are respectively abutted and fitted on the two side faces of the insertion part 302. Considering that a certain distance needs to be maintained between the coarse positioning and the fine positioning of the shell 300, the first positioning face 211 and the second positioning face 222 are generally arranged at the position of the bottom end of the mounting area 24, through the first positioning face 211 and the second positioning face 222, the insertion part 302 is completely limited in the mounting area 24 by the positioning plate 22 and the static mold 21, and the positioning is more accurate.

[0065] In a further embodiment, the bottom of the first positioning surface 211 extends toward the mounting area 24 to form a support portion 212, and the insertion portion 302 is inserted into the mounting area 24 and abuts against the support portion 212. Through the support portion 212, the insertion portion 302 achieves vertical positioning within the mounting area 24, resulting in more precise positioning of the scrap material 301 during cutting, thus improving the cutting effect. The cutting blade 41 of the cutting assembly 4 passes through the support portion 212 to enter or move away from the mounting area 24. Generally, the blade 411 of the cutting blade 41 adheres to the surface of the insertion portion 302 to achieve the best cutting effect.

[0066] In other embodiments, the housing scrap shearing device 100 further includes two end positioning pads 5, which are fixed to the fixing plate 1. The two end positioning pads 5 are perpendicular to the length direction of the mounting area 24 and are positioned outside the two limiting posts 23. Figure 1 When the housing 300 is positioned and clamped, the clamp-shaped side 303 of the housing 300 is usually in a suspended state. Considering that the plastic housing part in the cantilever state is prone to deformation under force, in order to avoid the deformation of the housing 300 exceeding the controllable range during the positioning and clamping process, which would damage the housing 300 or affect the shearing result of the remaining material 301, an end positioning pad 5 is set to support the bottom of the clamp-shaped side 303. When clamped, the bottom of the clamp-shaped side 303 abuts against the end positioning pad 5 to reduce the deformation of the clamp-shaped side 303.

[0067] In summary, the shell scrap shearing device provided by this utility model achieves coarse positioning by inserting the shell's plug-in portion into the installation area and abutting the shell against the limiting post. Then, by pressing down with a clamping mold, the inner side of the shell is made to fit against the outer surface of the stationary mold or positioning plate, achieving precise positioning and clamping. The shell with the clamp-shaped side achieves the clamping work before cutting through the above structure. The clamping structure is simple and the feeding efficiency is high.

[0068] Secondly, since the top pressure range of the clamping mold is close to the direction of the cutting force of the shearing blade, the remaining material of the shell is not prone to elastic deformation and displacement during cutting, resulting in excellent cutting quality.

[0069] In addition, the shell scrap shearing device described in this embodiment has a simple structure and low manufacturing cost.

[0070] Example 2:

[0071] exist Figures 1-6 Based on this, refer to Figure 7 This embodiment provides a shearing machine 200, including a frame 6, a transverse mechanism 7 and a pressing mechanism 8, as well as the shell scrap shearing device 100 described in Embodiment 1.

[0072] The rack 6 has a mounting portion 61 and a working space 62, the traversing mechanism 7 is arranged on the mounting portion 61, and the pressing mechanism 8 is arranged on the working space 62 and fixed to the mounting portion 61. The traversing mechanism 7 comprises a traversing platform 71 which can enter or leave the working space 62 in the horizontal direction. The pressing mechanism 8 comprises a pressing plate 81 which can move away from or close to the traversing mechanism 7 in the vertical direction. The fixed plate 1 is arranged on the traversing platform 71, and the clamping mold 3 and the shearing baffle 26 are arranged at the bottom of the pressing plate 81.

[0073] In the process of shearing the excess material 301 of the shell 300, the traversing platform 71 moves the positioning assembly 2 out of the working space 62 to provide sufficient space for placing the shell 300. After the shell 300 is placed on the positioning assembly 2 according to the position, the traversing platform 71 moves back, the pressing plate 81 drives the clamping mold 3 to move until the clamping mold 3 presses and clamps the shell 300. After the shearing of the excess material 301 is completed, the pressing plate 81 resets, and then the traversing platform 71 moves the shell 300 out of the working space 62 to facilitate the unloading work of personnel or personnel.

[0074] In some embodiments, a plurality of guide rods 82 are vertically arranged on the side of the pressing plate 81 facing the rack 6, the positioning assembly 2 is provided with a guide groove 25 matched with the guide rods 82, and the guide rods 82 are inserted into and limited in the guide groove 25, so that the clamping mold 3 is in close contact with the shell 300. Considering that the pressing surface 31 of the clamping mold 3 is in close contact with the upper surface of the shell 300, in order to avoid damage to the shell 300 when the clamping mold 3 presses the shell 300 due to assembly error of the pressing mechanism 8 or due to position deviation of the clamping mold 3. By arranging the guide rods 82 and the guide groove 25 and finely correcting the position of the clamping mold 3 before the clamping mold 3 abuts against the shell 300, the above-mentioned risk can be avoided.

[0075] In summary, the shearing machine provided in the embodiment has high efficiency and good consistency in shearing the excess material of the shell with the pincer-shaped side portion after the shell excess material shearing device of embodiment 1 is adopted, and the manufacturing cost of the equipment is low.

[0076] Embodiment 3:

[0077] On the basis of Figures 1-7 , referring to Figure 8 , the embodiment is adjusted on the basis of the shearing machine 200 provided in embodiment 2, and the difference lies in that a vacuum chuck 811 is further arranged on the side of the pressing plate 81 facing the rack 6, and the vacuum chuck 811 sucks the surface of the shell 300 to drive the shell 300 to separate from the mounting area 24 after the shell 300 finishes shearing the excess material 301.

[0078] When the shell 300 completes the shearing work of the excess material 301, it is considered that the plug-in part 302 may be tightly attached to the positioning plate 22 in the mounting area 24, or be tightly attached by the static mold 21, or be tightly clamped by the positioning plate 22 and the static mold 21, so that the shell 300 is inconvenient to be taken out from the shell excess material shearing device 100. The suction cup can suck the shell 300 during the resetting of the clamping mold 3, so as to facilitate the later discharging work.

[0079] Of course, in other embodiments, the suction cup can also be part of the automatic discharging mechanism. When the suction cup sucks the shell 300 and makes the shell 300 completely separate from the positioning assembly 2, the transverse platform 71 drives the positioning assembly 2 to leave the working space 62. At this time, the vacuum suction cup 811 stops working, and the shell 300 falls into the working space 62. The rack 6 can be provided below the working space 62 with a discharging mechanism or a finished product collector (not marked) and other functional components to realize the automatic discharging function of the shearing machine 200.
